This approach uses the resource loader to get the absolute path to a file in your app, and then goes up a few folders to the app's root folder. No servlet context required! This should work if you have a "web.xml" in your WEB-INF folder. Note that you may want to consider using this solely for development, as this type of configuration is usually best stored externally from the app.

public String getAppPath()
{
    java.net.URL r = this.getClass().getClassLoader().getResource("web.xml");
    String filePath = r.getFile();
    String result = new File(new File(new File(filePath).getParent()).getParent()).getParent();

    if (! filePath.contains("WEB-INF"))
    {
        // Assume we need to add the "WebContent" folder if using Jetty.
        result = FilenameUtils.concat(result, "WebContent");
    }

    return result;
}
